Why do light emitting diodes are preferred over conventional incandescent low power lamps? |
High operational voltage and less power Short life and ruggedness The bandwidth of emitted light is 10 nm to 50 nm Warm up time required |
The bandwidth of emitted light is 10 nm to 50 nm |
The correct answer is Option (3) → The bandwidth of emitted light is 10 nm to 50 nm The bandwidth of LED is 10 nm to 50 nm, making them ideal for specific applications like displays and lightning where color precision is important. |
